The leaders of New Zealand and Papua New Guinea (PNG) will look at ways to strengthen trade and other bilateral ties during talks this week in New Zealand. New Zealand Prime Minister John Key said Monday that Papua New Guinea Prime Minister Peter O\'Neill would make his first bilateral visit to New Zealand when he arrived for a three-day stay on Wednesday. \"Papua New Guinea is an important partner in the Pacific and Asia-Pacific region and I look forward to having constructive discussions with Prime Minister O\'Neill,\" Key said in a statement. Both governments were encouraging greater commercial ties with a double tax agreement going through the final stages of ratification. \"There are huge opportunities for New Zealand businesses in Papua New Guinea. The tax agreement will help facilitate trade between both countries,\" Key said. \"New Zealand also supports a large aid program in Papua New Guinea. We are sharing our expertise in renewable energy and agricultural production and distribution with Papua New Guinea.\"
